Discussion about customizing openX advertising software

We are developing a U.S. classifieds website using GeoCore Classifieds ([login to view URL]) and we'd like to consider using the openX advertising software to sell and manage display ads. The software must be able to uniquely price ads based on the following three parameters: 1) Region: State and City 2) Page: Homepage, about us, category, subcategory pages, etc. 3) Zone: Place on a page (header, footer, side, etc.) The purpose of this small project is to have a one hour conversation (Skype or phone) about openX and how we can customize it to meet our classified needs and to also see your skill level with the openX software. If you think you are someone who can build this for us or at least get it moving in the right direction, then please reply with your credentials and an example of a site you've built using openX as the advertising engine. Thanks for taking the time to read this job post and we hope to hear from you soon.
